Hey if you’re from Ontario, I found a book called “60 kayaking routes in Ontario” or something along those lines. The book shows the difficulty level and other info. I’m a beginner as well and might get that one.
Edit: my mistake it’s for Canoes. But I’m guessing that means the routes are nice and stable for a kayak as well.
